Dynamics 365 CRM – How to Retrieve Entity Information in JavaScript

When developing customizations in Microsoft Dynamics 365 CRM, one of the key aspects is being able to retrieve information about the current record on a form. This is essential for implementing custom logic, making API calls, or integrating with external systems.

In this article, you’ll learn the most important properties you can use in JavaScript within Dynamics 365 CRM, along with code examples you can apply directly in your projects.

Most Commonly Used Properties in Dynamics 365 CRM JavaScript Forms

1. EntityId

Returns the unique identifier (GUID) of the currently open record. This is critical for API calls or any record-specific operations.

var entityId = Xrm.Page.data.entity.getId();
console.log("EntityId:", entityId);

2. EntityIdWithoutBraces

Retrieves the record’s GUID without curly braces { }, which are often not accepted in service calls or integrations.

var entityId = Xrm.Page.data.entity.getId().replace(/[{}]/g, "");
console.log("EntityIdWithoutBraces:", entityId);

3. EntityName

Returns the logical name of the entity (e.g., account, contact, opportunity). This is particularly useful for dynamically identifying which entity the script is running on.

var entityName = Xrm.Page.data.entity.getEntityName();
console.log("EntityName:", entityName);

4. EntitySetName

Retrieves the OData entity set name (e.g., accounts, contacts). This is necessary when working with the Web API or OData queries.

var entitySetName = Xrm.Page.context.getQueryStringParameters()["etn"];
console.log("EntitySetName:", entitySetName);

5. IsDirty

Indicates whether the form has unsaved changes. It returns true if there are pending modifications and false otherwise. This helps prevent users from closing the form without saving.

var isDirty = Xrm.Page.data.entity.getIsDirty();
console.log("IsDirty:", isDirty);

6. AttrName (Primary Attribute)

Retrieves the value of the entity’s primary attribute, such as Name in account or contact. This is commonly used for display purposes or to add validation logic.

var attrName = Xrm.Page.getAttribute("name").getValue();
console.log("Primary Attribute (Name):", attrName);

Best Practices When Working with Properties in D365 CRM

  • Always use the modern API (formContext) instead of Xrm.Page, as the latter is deprecated.
  • Validate if a value is null or undefined before applying your logic.
  • Use EntitySetName to properly construct your Web API queries.
  • Take advantage of IsDirty to improve user experience and prevent data loss.

Conclusion

Mastering these properties will allow you to build more robust and efficient scripts in Dynamics 365 CRM. Whether you need to identify a record, validate unsaved changes, or interact with the Web API, these functions are the foundation of any advanced customization.

By implementing them correctly, you’ll improve user experience and make integrations with other systems much easier.

Dynamics 365 Web API: How to Perform Multiple POST or Upsert Operations

Dynamics 365 Web API: How to Perform Multiple POST or Upsert Operations Dynamics 365 Web API: How to Perform Multiple POST or Upsert Operations The Dynamics 365 Web API provides a powerful way to interact with data in a structured and scalable manner. Among its most efficient — yet often underutilized — capabilities is the ability to perform multiple record operations (batch requests) or upserts (insert or update) in a single call. This article walks you through how to correctly build URIs, structure JSON payloads, handle lookup bindings using @odata.bind , and understand how Dynamics 365 interprets and processes these requests internally. 🧩 1. What Is an Upsert Operation? An Upsert is a hybrid between two common database operations: Insert (POST): Creates a new record. Update (PATCH): Updates an existing record. Dynamics 365 automatically determines whether to insert or update based on whether a record with the specified Alternate Key already exists. ...

Dynamics 365 CRM – Managing Translations in JavaScript with RESX Files

Dynamics 365 CRM – Managing Translations in JavaScript with RESX Files Dynamics 365 CRM – Managing Translations in JavaScript with RESX Files In multi-language environments within Dynamics 365 CRM , it is common to display localized messages in alerts, pop-ups, or validation logic. A robust solution is to use .resx resource files together with Xrm.Utility.getResourceString in JavaScript. Retrieving a Translation The standard pattern to retrieve a translated message is: Xrm.Utility.getResourceString( namespace.localization.webResourceName, namespace.localization.messageKey ); webResourceName : the name of the .resx resource file, without specifying a language ID. Dynamics automatically loads the correct language based on the user’s settings. messageKey : the key defined in the .resx file that contains the translated message. Best Practices for Structuring Keys Organizing translations in a c...

SSIS (.dtsx in Visual Studio) vs XrmToolBox — Data Transporter

SSIS (.dtsx in Visual Studio) vs XrmToolBox — Data Transporter SSIS (.dtsx in Visual Studio) vs XrmToolBox — Data Transporter Technical Comparison and Practical Guide for Moving Data Between Dynamics 365 / Dataverse Environments Moving data between environments (dev → test → prod) is something every team working with Dynamics 365 / Dataverse does frequently. There are two common operational approaches: Classic SSIS (Visual Studio .dtsx packages with Data Flow, Lookups, Scripts, SQL staging, etc.) — an industrial ETL/ELT approach. XrmToolBox – Data Transporter (a lightweight plugin for copying records between organizations) — a manual, fast, developer-oriented approach. Below we break down the real differences, risks, and practical recommendations for each method. 1) Architecture and Philosophy SSIS (.dtsx in Visual Studio) ETL/ELT architecture: connect to sources (SQL, CSV, APIs), transform (Derived Column, Lookup, Script Component) and load into Dat...
